Abstract: A retaining mechanism includes a retainer with a skirt that has a surface of revolution with an axis of rotation. The skirt extends 180.0 degrees or less about the axis of rotation, forming a thru-slot. A drive portion extends axially from the skirt.

Abstract: A lock assembly for attaching a wear member to a base includes a threaded retaining block with a C-spring attached to the retaining block that fits into an aperture of the base. A threaded lock pin fits into the aperture of the wear member, and the threaded aperture of the retaining block, retaining the wear member onto the base. The threaded lock pin engages the C-spring that prevents unintentional rotation of the threaded lock pin so that the threaded lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.

Abstract: A lock includes a drive portion and a pin receiving portion. The drive portion includes a polygonal aperture, and the pin receiving portion includes a hole with an internal surface of revolution that defines an axis of rotation, a radial direction, a circumferential direction, and a slot extending at least partially through the pin receiving portion into the hole.

Abstract: Method of manufacturing first structural component for or joining with second structural component by groove weld is provided. The first structural component has first surface, second surface and end portion. The component is bent at end portion to form bent portion defining convex and concave faces. First portion of bent portion is removed at convex face in form outer weld surface having first face extending from first surface, and second face connected to first face. Second portion of bent portion is removed at concave face to form inner edge surface having arcuate profile. Inner edge surface extends from second surface and connects to second face via transition portion. A portion of first face, second face, transition portion, and inner edge surface define root protrusion, having a root protrusion height, for first structural component. The root protrusion defines stress protected weld root region isolated beyond and away from root stress flow path.

Abstract: A mobile machine track shoe includes a ground engaging surface including a first grouser bar and a second grouser bar substantially parallel to the first grouser bar. The track shoe further includes a base opposite the ground engaging surface. The base includes a first relief disposed opposite the first grouser bar, and a second relief disposed opposite the second grouser bar.
